Using the method of frame type hydraulic machine: Nantong techneat forging machine

1, frame hydraulic machine operators must be trained to master the equipment performance and operation skills, in order to work independently.

2, before the operation, should first clean up the mold on a variety of debris, wipe the hydraulic machine rod any dirt.

3. The frame hydraulic press installation die must be in the case of power failure, no collision start button, handle and pedal on foot switch.

4. Fit the upper and lower dies, adjust the clearance of the mold, not allow unilateral deviation from the center, confirm the fixed die and try again.

5, frame hydraulic machine before work, first start the equipment idling for 5 minutes, while checking the fuel tank oil level is enough, the sound of the pump is not normal, hydraulic units and pipes, joints, pistons are leaking.

Start the equipment pressure test, check whether the pressure reaches the working pressure, whether the equipment is normal and reliable, whether there is leakage or not. 7, adjust the work pressure, but should not exceed 90% of the equipment rated pressure, test a piece of work, inspection qualified reproduction.

For different hydraulic press profiles and workpieces, press and correct the press, shall adjust the working pressure and pressure, the number of times and the time of the press at any time, and ensure that the mold and workpiece are not damaged.

In the quality level, with the continuous improvement of product quality requirements, the domestic hydraulic machine manufacturers pay more and more attention to the quality of products. As the domestic hydraulic press technology was introduced and absorbed by the former Soviet Union, the domestic hydraulic press is far superior to the Japanese and Korean products in stiffness and strength, which is similar to the products in Europe and america.

Frame hydraulic press has two types of vertical and horizontal. Most hydraulic machines are vertical and the hydraulic press is horizontal. According to the structure type, the hydraulic press has double column, four column, eight column, welding frame and multilayer steel belt winding frame, etc. the medium and small vertical hydraulic press can also use C type frame. The frame hydraulic press structure is a frame type whole welding, which has the advantages of high strength, good stability, low energy consumption, low noise, convenient operation, easy maintenance, economy and durability. C type frame hydraulic machine, three sides open, easy to operate, but the rigidity is poor. It is suitable for pressing, correcting, stretching, bending, forming, blanking, flanging and other stamping processes. It is also suitable for pressing process such as powder metallurgy, auto parts, household appliances, kitchen utensils and so on. Press welding frame hydraulic press, rigid, front and back open, but left and right closed. In the vertical vertical four column free forging hydraulic press, the oil cylinder is fixed in the upper beam, and the plunger is rigidly connected with the movable crossbeam, and the movable crossbeam is guided by the column and moves up and down under the action of the pressure of the working fluid. The crossbeam is provided with a worktable that can move back and forth. An upper anvil and a lower anvil are respectively arranged on the movable crossbeam and the work table. The working force is made up of the frame composed of the upper and lower beams and columns. The large and medium-sized free forging hydraulic press driven by pump accumulator adopts three working cylinders to obtain the three stage working force. A balancing cylinder and a return cylinder are also arranged outside the working cylinder.

Frame hydraulic press is used for forging and forming, and hydraulic press can be used for straightening, pressing, packing, pressing block and pressing board. The hydraulic press includes a hydraulic press and an oil press. Water based liquid as working medium is called water press, and oil as working medium is called hydraulic press. General specifications of hydraulic machine with nominal work force (KN) or nominal tonnage (ton) said. Forging hydraulic press is mostly hydraulic press with higher tonnage. In order to reduce the size of the equipment, large forging hydraulic press is usually used at higher pressure (about 35 MPa), and sometimes more than 100 mpa. Other uses of hydraulic presses generally use 6~25 MPa operating pressure. The tonnage of the hydraulic press is lower than that of the water press.

1, the body pressure plate sliding up and down, it is strictly prohibited to hand and head into the press plate, mold parts.

2, strictly prohibit the pressure at the same time, the work of percussion, stretching, welding, bending, twisting and other operations.

3, hydraulic press machine, welding, welding around are not allowed to smoke, do not store flammable and explosive materials. Fire prevention measures.

4, hydraulic machine is completed, the power should be cut off, the hydraulic rod will wipe clean, good lubricating oil, will die and workpiece clean, tidy

5 、 in use, if the machine running is not normal, should immediately cut off the power supply, stop inspection.

6, the adjustment of machine tools, you must cut off the power supply, moving the workpiece should pay attention to hand safety.

7. Each part of the machine tool should be kept lubricated. The hydraulic machine should be filled with lubricating oil each time by the operator, and the lubricating oil should be filled once every half year by the mechanic to the rolling bearing part.
